Are external sun window screens an effective shading device?

The sun window screens for the exterior are highly efficient. I, Josh Hobbs, offer outdoor shading for windows using either an 80% or 90% fabric.


A person holds mesh screens with 80% and 90% shade above concrete. Shadows and text indicate shade percentages.

Here are two outstanding photos that highlight the differences between 80% and 90% shading fabrics, demonstrating their distinct features and the shade each provides. The first image shows the 80% and 90% shading fabrics in comparison to 100%. The 80% fabric lets 10% more sunlight pass through while still providing significant protection from direct rays. This shading level is often perfect for the North, South, and Eastern sides.

The second image displays the 80% and 90% sun shading fabric set against a textured grass background. The 90% fabric is perfect for windows facing west, which endure intense sunlight. Sometimes, people like to use the 90% fabric for their east-facing windows as well.


Both photos not only showcase the visual distinctions between the two shading options but also demonstrate how each fabric can affect the ambiance inside the home. By comparing these images, one can better understand how solar shading fabrics can be used to improve comfort and shield against the elements in different environments.



Can external sun window screens reduce energy costs?

We are frequently asked this question. It's crucial to understand that providing precise figures, such as percentages, is not feasible because each situation varies. Every home has a different number of windows, as well as a varying number of windows and sizes facing West. Additionally, there are many different types of windows available. There are shade trees in front of some, but not others. Each home certainly has a different number of windows. It's not accurate to universally claim that all Austin, TX solar screen installations will reduce your utility usage by 30%, as many websites do. Such statements are simply irresponsible. My customer review page has 100's more just like these for you to see yourself how efficient external sun window screens are at keeping your home cooler.





Assessing the Energy Efficiency of external sun window screens from one man's extensive experience.


I am thrilled to share our incredible success story with your exterior sun screen shades! We've experienced substantial savings from your sun screens on our electricity bills during the scorching summer months. Attached is a screenshot from our PEC usage analyzer, showcasing a remarkable drop in usage for June, July, and August of this year. This impressive reduction occurred without any other conservation methods or changes in our usage patterns. We can largely attribute this fantastic decrease in electricity consumption to the solar screens, resulting in tangible monetary savings. We've saved an amazing $150 to $200 per month from June to August, and we've noticed smaller savings in the following months. At this rate, the screens will pay for themselves much sooner than I initially expected!


Additionally, my wife and I are passionate bird enthusiasts. Before installing the screens, we often experienced bird strikes on our windows. Since installation, this issue has completely disappeared. The birds we feed also seem to adore your screens!

My solar screens are also very effective at shading commercial windows.

I am an Austin, TX, commercial solar screen installer as well as a residential installer. My solar screens are installed on commercial windows all over Austin.

In addition to shading commercial windows from the outside, I also shade them from the inside with my business window blinds. I provide interior window shades for offices, restaurants, bars and commercial buildings all over the Austin area.





I also install my solar screens for apartment buildings

My solar screens not only make Apartment buildings look good, but they are extremely effective at cooling off the units.


Apartment solar screens can be a very cost-effective solution to making a significant improvement to your community.


If you have old bug window screens, consider replacing them with new solar screens for not all that much more.


Additionally, I shade patios with custom-made shades that I make right here in Austin, Texas.

In Austin, Texas, I manufacture my own manual line of solar sun shades for patios, crafted from a dense fabric that offers 97% shade coverage. These patio shades are designed to provide excellent visibility while effectively blocking sunlight. Additionally, the pricing for my outdoor roller shade blinds is highly competitive, making them an attractive option for enhancing outdoor spaces.
